Running a Biocrypt or Fingerprint Device With Webservice App Without OS Possible?

Hi Friends.,

Is it possible to Run an electronic device(for example finger print device,biocrypt device)run with webservice application without OS.CAn i do this,is it possible.Please clarify this doubt.

Thank you.

Well, it is possible, in that whatever the software (or firmware) runs in it may not qualify as a "proper" OS. Microcontrollers have programs in them which run whenever they are powered up, so in that sense they do have a rudimentary OS - just that it does nothing but run the uC, restricted to very specific I/O tasks (low-level hardware signalling) and does not provide any API or platform to host other programs, nor does it have any kind of memory management. This is basically somewhat similar to the BIOS - its definitely not an OS but is a program nevertheless.
